Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (screwdrivers, socket set).
Safety Warnings: Always engage the parking brake and use wheel chocks to prevent the vehicle from rolling.

2. Clear Codes

Use the OBD-II scanner to clear any existing trouble codes after addressing the underlying issues.
Start the vehicle and check if the warning lights remain illuminated.

3. Replace Faulty Components

Wheel Speed Sensors:
- Disconnect the wiring harness from the faulty sensor.
- Remove the mounting screws and take out the sensor.
- Install the new sensor, secure it with screws, and reconnect the wiring harness.
ABS Module (if necessary):
- Disconnect the battery to avoid electrical shorts.
- Remove any mounting bolts securing the ABS module.
- Disconnect the wiring harness from the module.
- Install the new ABS module, reconnect the harness, and secure it with bolts.

4. Brake Fluid and System Bleed

Check the brake fluid level; refill if necessary using the recommended brake fluid type (DOT 3 or DOT 4).
Bleed the brake system to remove air, starting from the furthest wheel from the master cylinder to the nearest.

5. Test Drive

Perform a test drive to ensure the brake system is functioning correctly and observe for any warning lights.
